JAMES BUCKLER, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CROMPTONKNOWLES LOOlVI WORKS, A CORPORATION OF MASSACHUSETTS.

FILE-FABRIC LOOM.

To all whom it may concern:

Be it known that I, JAMES BUCKLER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPile-Fabric Looms, of which the following is a specification.

My invention relates. to pile fabric looms, and particularly to a loopcutting niachanisni for that class of pile fabric or carpet looms, inwhich needles or wires are used over which the loops are formed; saidneedles or wires extending in the direction of the length of the fabric,and the loops also extending in the direction of the length of thefabric.

In looms of the class referred to, as ordinarily made, there is a seriesof cutters, which consist of cutters or knife blades removably supportedin holders which have rounded needle shaped ends which extend into theloops of the fabric, and the loops are out by the blades as the wovenfabric moves toward them, all as fully shown and described in U. S.Letters Patent N o. 7 58,968, to which reference is made.

In my improvements I do away with the stationary cutters or knifeblades, and substitute therefor rocking cutters or knives, which arelocated above the ordinary knife blade holders.

I have only shown in the drawings a detached portion of a loom of theclass referred to, with my improvements applied thereto, suflicient toenable those skilled in the art to understand the construction andoperation thereof.

Referring to the drawings :Figure l is a plan view of my improved loopcutting mechanism, combined with parts of a loom, and showing a detachedsection of the pile loop fabric, with some of the loops cut, and lookingin the direction of arrow a, Fig. 2, and, Fig. 2 is a section, on line2, 2, Fig. 1, looking in the direct-ion of arrow 6, same figure, andalso shows a portion of the loom sides with operating levers; the brokenlines show a different position of the cutting mechanism.

In the accompanying drawings, 1 is the loom side or end frame, 2 is thebreast beam, 3 is the breast beam plate extending upon and attached tothe upper side of the breast beam,

and over which the pile fabric l passes to the take-up roll, not shown.

5, in Fig. 2, represents the end of a pile wire or needle, over whichthe loops 1- of the pile fabric 4: are formed in the well known way, andas fully described in said Patent No. 7 58,968, above referred to.

At the front of the breast beam 2, and secured on an extension 2thereon, is an augular bar 6, which extends transversely across the loomand has fastened thereon, in this instance by screws 7, bars or plates7, which in this instance are made as separate plates, and the inneredge of which forms a stop or rest for the knife guides or holders 8.The knife guides or holders 8 are in this instance made separate fromthe pile wires or knives 5, and are preferably made of sheet metal, cutin the desired shape and bent along the middle portion, and the twoparts brought together to form a guide or holder for the knife blade,and the extended inner end rounded or made needle shape, as shown at S,to extend into the loops 4 of the pile fabric 4. The enlarged end of theknife guides 8 have in this instance a pocket or opening 8 therein, seeFig. 2, into which loosely extend the loop cutters or knives 9. Theknife guides or holders 8 have a lateral movement in the direction ofthe width of the fabric.

The knives 9 have their cutting surface on their lower edge, instead ofon their front edge, as is customary, and in this instance theirupwardly extending portion is made hook shaped, as shown at 9, in Fig.2. The hook shaped ends 9' are preferably loosely supported in a recess10 in the bar 10, which bar extends transversely across the loom and issupported at its center part on a support 11, and at its ends on aclownward extension 12' on a rock shaft 12. A series of caps or holders13 are fastened to the bar 10, by screws 13 or otherwise, and act todetachably attach the knives 9 to the transverse bar 10, and to hold theknives 9 in their proper position, but allow a lateral movement of saidknives with the guides or holders 8. By removing a cap or holder 13 anyone of the knives 9 may be detached from the bar 10 and removed, withoutremoving any of the other knives. The center support 11 has its hubs 11fast upon the rock shaft 12. A center bracket 14 carries the rock shaft12, and has its foot 14 secured on the angle bar 6, by bolts 15, orotherwise. The end of the rock shaft 12 has mounted thereon the hub 16of a lever 16, which lever is pivotally attached to the upper end of thedownwardly extending connector 17 the lower end of the connector 17 ispivotally attached to one arnrof bell crank lever 18, the hub 18 of saidlever is loosely pivoted on a stud 19 on the loom side 1. The other armof the bell crank lever 18 has connected thereto a connector 20, theother end of the connector 20, not shown, is pivotally attached to thelay sword, not shown, to move with said lay sword, and rock the shaft12, and with it the knife bar support 10 and the knives 9, as shown bybroken lines in Fig. 2, to cut the loops 4 of the pile fabric 4.

It will be understood that the details of construction of myimprovements may be varied if desired, and they may be adapted to beused on different kinds of pile fabric looms of the class referred to.

Having thus described my invention,what I claim as new and desire tosecure by Letters Patent is 1. In a loop cutting mechanism for pilefabric or carpet looms, having needles or wires extending in thedirection of the length of the fabric, over which the loops are formed,a plate or plates extending transversely across the loom, the inner edgeof which forms a stop for a series of knife guides or holders, and saidknife guides or holders for a series of cutters or knives, and saidcutters or knives, having a cutting surface on their lower edge, andtheir upper ends of hook shape and extending into a recess in a barextending transversely across the loom, and said bar, suitablysupported, and one or more detachable caps or holders to hold thecutters or knives in their proper position, and means for communicatingto said knife supporting bar and said cutters or knives a rockingmovement to cut the pile loops.

2. In a pile fabric loom having needles or Wires extending in thedirection of the length of the fabric, and a loop cutting mechanism tocut the loops on thefabric, a bar or plate extending in the direction ofthe length of the loom, and secured upon the breast beam, one or morebars or plates secured upon said first mentioned bar, the inner edge ofwhich forms a stop for a series of knife guides or holders, and saidknife guides or holders, for a series of cutters or knives, and having areduced portion to extend within the loops on the fabric, and

free at their outer ends to move in the direction of the width of thefabric, and said cutters or knives, having a cutting surface on theirlower edge, and their upper ends of hook shape and extending into arecess in a bar extending transversely across the loom, and said bar,suitably supported, and one or more detachable caps or holders to holdthe cutters or knives in their proper position, and means forcommunicating to said knife supporting bar and said cutters or knives, arocking movement to cut the pile loops.

3. In loop cutting mechanism for pile fabric looms, a series of knifeguides or holders for a series of cutters or knives, and said cutters orknives, having a cutting sur face on their lower edge, and their upperends of hook shape and extending into a recess in a bar extendingtransversely across the loom, and said bar, suitably supported, andmeans for communicating to said knife supporting bar and said cutters orknives, a rocking movement to cut the pile loops.

1. In loop cutting mechanism for pile fabric looms, a plate 01' platesextending transversely across the loom, the inner edge of which forms astop or rest for knife guides or holders, and said knife guides orholders, for a series of cutters or knives, and having a reduced portionto extend within the loops on the fabric, and said cutters or kniveshaving a cutting surface on their lower edge, and their upper ends ofhook shape and extending into a recess in a bar extending transverselyacross the loom, and said bar, and means for communicating to said knifesupporting bar and said out ters or knives, a rocking movement to cutthe pile loops.

5. In a loop cutting mechanism for pile fabric looms, a series of knifeguides or holders for a series of cutters or knives, and said cutters orknives having a cutting surface on their lower edge, and their upperends detachably attached to a bar extending transversely across theloom, in such a manner that any one of said knives may be removedwithout removing the other knives, and said bar suitably supported, andone or more detachable caps or holders, to hold the cutters or knives intheir proper position, and means for communicating to said bar, and saidcutters or knives, a rocking movement to cut the pile loops.
